Apple has updated its MacBook line of laptops, it announced at WWDC in San Francisco. Both the MacBook Air and MacBook Pro ranges have been refreshed, adding Ivy Bridge processors from Intel and a raft of other improvements.

The new MacBook Airs get USB 3 ports and the option of a bigger 512GB SSD hard drive. They can be specc'ed up to a 2.0GHz i7 dual-core processor, with Turbo Boost up to 3.2GHz.

The 11 and 13-inch machines can also carry up to 8GB 1600MHz memory, and feature up to 60 per cent faster graphics in comparison to former models. And the FaceTime camera is now upgraded to 720p.

They will cost £849 to £929 for the 11-incher depending on specifications and £999 to £1,249 for the 13-inch Air.

The MacBook Pro models have also been improved. They too feature USB 3 ports, and the faster processors (up to 2.7GHz quad-core i7 processor), but add Nvidia GeForce GT 650M (Keplar) graphics processors into the mix.

Coming in 13 and 15-inch sizes, they will be available for £999 to £1,249 for the 13-incher, £1,499 to £1,799 for the 15-inch version.

All the new MacBooks will be available from the Apple Store today.
